At their ends the condenser sections are connected by headers 28 and 29' flowing to. the inner chamber 15 is also subjected to the. wall or shell 13 cooled'by' the water within the space 16 and conslderable condensation takes place. The remaining'steam then flows through the water in the space 16 and whatever steam is left will strike the extensive surface of the cover structure so thatgonly a very small amount,

if any, of steam will ever reach the vent'18.

The condenser structure canbe dimensioned so that the loss of water in the form of steam will be practically negligible. The con ldensed steam is added to the water in the reservoir .which feeds to the water jacket of the engine. Instead of the two concentric steam or condenser chambers shown, there may be a greater number with air circulating passageways between them. Thesupply of cooling water can also be increased by increasing the depth of the tank 12.

thecondenser structure is separate from the water' supply space or reservoir 26. The condenser'structure comprises a series or tier of condenser chambers or sections 27, As shown these sections are parallel and tilted respectively. At its lower corner the condenser structure is connected by pipe 30 with the lower end of the water tank and the upper corner of the condenser structure is connected by pipe 31 with the upper end ofithe engine wateriacket. A pipe 32 connects from the bottom of the water tank to the lower end of the water jacket. J The engine is not shownin Fig. 2, but the connections of the pipes 31' and 32 with the engine are the same as the connections in-the pipes 24 and 25 in the arrangement of Fig.

1. The steam flows from the enginejacket through the condenser sections where 'it'is subjected to the cooling influence of the air flowing through the passageways between the sections, the uncondensed steam flowing through connection'30 into the tank 26 and through the water therein to be finally condensed. Any wind, either natural or forced,

toward the low end of the condenser sections will increase the circulation of air between the sections and thereby increase the condensing efliciency. Under ordinary conditions, however, the natural draft will be suflicient to give the desired condensation.
